In a FH video, a voice actor mentioned there was a toilet RP... although I don't know how toilets RP?
The spotless rimmed porcelain throne awaited for the next human to be used by, knowing that is was the only clean toilet in the restroom left, there had to be a chance for it to be used. "Flush" went the Kohler in the stall next to itself.
I don't know, but that's how I would RP as a toilet. xD
Other than that, I truthfully never saw any weird RPs, or at least I can't remember the last weird RP I saw.
